LAKE COUNTY, Calif. — The Lake County Vector Control District said West Nile virus has been detected in two more mosquito samples and also in sentinel chickens in Lake County.

The sentinel chickens were in a flock near Upper Lake. The mosquitoes, all Culex tarsalis — the western encephalitis mosquito — were collected in traps set in Lower Lake and Upper Lake, the district reported.

Earlier this summer positive mosquitoes were collected near Kelseyville and Upper Lake, the district said.

“When we see West Nile virus in sentinel chickens, that tells us that the conditions are right for human infections of West Nile virus,” said Jamesina Scott, Ph.D., district manager and research director of the Lake County Vector Control District. “The best protection from West Nile virus is prevention. It’s important to avoid mosquito bites.”
